meets the lintel at 46-, so that the joints between said plates and thelintel bottom are not in line. I 1 3 On the outside of the lower rail offrame 40 is Welded the plate 47, which "forms a meeting rail. A flatplate 48 at its lower To 'theside rails of frame 49 are welded wideplates '49, Fig. 2, which enter compart- .ment E through the clearancebetween the inner plate 27 and the edge of plate 29, and K extendoutwardly to jamb 'wall C, Fig.2.

.On the side rails of frame 40 are adjustable weather-plates 50, securedby screws 51.

On frame 52 of lower sash H is a meeting rail plate 53 which lapsover-meeting rail plate 47 of the upper sash. A plate 54 on the lowersash meets the under surface of said meeting rail 53. On the outside ofthe lower rail of said frame is welded late 55 which extends below saidrail and ears against the vertical face of-a shoulder 56 formedon thesill B. On the inside of said lower rail is detachably secured --a plate57, the lower edge of which is flush with the bottom edge of said lowerrail, and the inner side of which meets the outer face of a flange 57*on said sill. I

On the outside of each vertical side rail of frame 52 is Welded a wideplate 58 which enters'coinpartment F through the clearance between theturned over edge 32 of plate 31 and the edge of plate 39 and extendsoutwardly to the jambwall C, Fig. 2.

On the inner face of each vertical side rail of frame 52 and disposedbetween the for the counter-weights, and third, to enable them toreceive the plates 49 and 58.

The plate 31 is removable in order to reach the sash weights bywithdrawing bolt 34. By removing plate 31, I can easily take out sash Hfrom the frame. -Then by taking out bolt 38* which secures baffle-plate38 to outer plate C, I can also easily remove sash G from the frame. Byloosening screw bolt 34, I can slide plate 31 upon plate C,

and thus adjust the openings receiving the plates 58. and 49 to suitvariations in thickness of sash. This I can do best when the plate 38is, as described, made of less thickness than the other plates, so as torender it flexible. Then when the plate 31 is moved to compensate foraless thickness of sash than is indicated in Fig. 2, the flanged over1,222,aos

edge 32 of said plate pushes against plate 58, thus carrying that plateagainstrthe edge of plate 39, which yields becausev of the flexibilityof plate 38, and reduces the Width of the opening which receives plate49 on sash G. I

The principal permanent joints are be tween the vertical edges of wideplates 49,-

58 and. the inner faces of the jamb plates O, D, and not between'th'evertical edges of the sash frames and the Window frame. Owing to thepresence of the baflle-plate 38, which separates compartments E and F,any draft entering through the opening in front of plate 49, forexample, wouldhave to travel across the compartment E,

through the joint at the edge of plate 49' and then back and escapethrough the same opening on the rear of plate 49. This, however, isprevented by the weather-plate 50' which. makes a joint with the plate39. In

order to fit the sash in the frame, all that is necessary is toadjustthe edges of the plates 49,58 to fit against theouter plates O and3 move the weather-plates 50, 5.9 to fit against plate 39. Any wear ordislocation due to settlement of the building is easily provided [Iclaim: -1.
